摘要:
Disclosed is a system and a method for minimizing signal interference for a broadcasting and communication convergence section within a local area, and an apparatus applied to the same. The system has a construction of mounting a plurality of multi RF (Radio Frequency) channels within a local area wireless communication apparatus located in a local area and minimizing signal interference between mutually adjacent RF channels within the local area wireless communication apparatus in a standard for providing a broadcasting and communication convergence service. Accordingly, it is possible to remove the mutual channel effects affecting a communication signal without signal interference for adjacent channels due to a broadcasting signal and it is not necessary to enhance a filtering characteristic for the adjacent channels of a chipset, which corresponds to a broadcasting and communication convergence standard structure in a local area, so that there is an advantage of reducing network investment costs.
